Justification of Red List Category
This species is classified as Near Threatened because forest within its small range is being lost through clearance for plantations and farming. However, the range is not yet severely fragmented or restricted to a few locations.
The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
There are no data on population trends; however, habitat loss and degradation within the species range is suspected to be causing a slow to moderate decline and range contraction.
Vireo osburni is endemic to Jamaica where it is uncommon; however it occurs singly and is secretive, so may conversely be largely overlooked (BirdLife Jamaica in litt. 1998). It occurs widely in upland forest, such as in the Blue and John Crow Mountains, Cockpit Country and Mt. Diablo (Downer and Sutton 1990, Stattersfield et al. 1998).
Blue Mountain Vireo inhabits humid and moist montane limestone forest (Brewer 2018). The species has also been found in upland woodland and shaded coffee plantations, suggesting some tolerance of habitat degradation (Bond 1982, Haynes et al. 1989, Brewer 2018).
Widespread habitat destruction has resulted in significant range contractions (Bond 1982, Haynes et al. 1989). Habitat loss has been primarily caused by the establishment of plantations (mostly coffee and Caribbean pine Pinus caribaea), the logging of trees for charcoal-burning, fires, small-scale farming and clearance for development (Dinerstein et al. 1995, Brewer 2018).
